Application filed May 11, 1914.. Serial No. 837,757.

To all whom it may concern:

Be it known that we, HENRY C. BOUR- UIN, residing at St. Marys, in thecounty of Auglaize and State of Ohio, and HARRY B. BOURQUIN, residing atSpringfield, in the county of Clark and State of Ohio, both citizens ofthe United States, have invented certain new and useful Improvements inDevices for Casting Ornaments in Fork of Plastic Material, of which thefollowing is a specification.

This invention relates to improvements in devices for casting ornamentsin work of plastic material.

The object of the invention is to provide for relieving the plainappearance of plastic material, such as structures of different kindsformed from cement, by introducing therein ornaments or embellishmentsin the nature of glass, porcelain, or other material of that kind, whichwill be cast into the plastic material in a manner to be partiallyexposed on the outer surface thereof.

A further object of the invention is to further carry out the foregoingidea by introducing into the walls of hollow plastic material worxornaments which will be transparent in their nature, such as coloredglass, in a manner to be exposed on the exterior of the structure and toalso communicate with the interior thereof so that by illuminating theinterior of the structure, a pleasing effect will be presented to theexterior; the more particular object being to provide embellishments orornaments of colored transparent material formed in different designs inthe plastic material structure.

A further object of the invention is to provide simple and effectivedevices for molding structures formed of plastic material and providingthe same with ornamentations of a different material to give to theplastic material a pleasing effect.

The invention consists in the constructions. and combinations of partshereinafter described and set forth in the claims.

In the accompanying drawings, Figure l is a vertical sectional view of amold and its core with the casting ofplastic'material and its ornamentsshown therein. Fig. 2 is a section on the line 2+2 of Fig. 1. Fig. 3 isa detail sectional view of a portion of the mold, the casting and one ofthe ornaments. Fig. 4c is a section on the line H of Fig. 1.

Fig. 5 is a detail sectional view of a portion of the mold, the castingand one of the ornaments, showing a removable bushing. Fig. 6 is asection on the line 66 of Fig. 5.

Like parts are represented by similar characters of reference in theseveral views.

In the particular construction shown in the drawings, there isillustrated a mold for casting hollow spheres of plastic material andfor also casting therein ornamentations in the nature of a series ofjewels formed from colored glass, which will extend about the peripheryof the finished product. It will be understood, however, that that isbut one form of the invention, as castings of plastic material in otherforms, both solid and hollow, may be constructed in accordance with ourinvention.

In the said drawings, 1 represents the walls of the mold proper whichare formed in sections held together during the molding operation bysuitable well known looking devices (not shown), a circular opening 2being left at one point for the purpose of pouring the cement. In thepresent case we have shown the core made up of a series of sections, inthe present case ten sections being employed. The exact shape and sizeof these sections is immaterial, it being sufficient to say that thesections will be made small enough to be removed through the opening 2after the plastic material has set and will be of such form as toprovide for different thicknesses in the wall of the plastic materialstructure. For instance, it is desirable that the walls at that pointwhere the ornaments are placed shall be of the least thickness, so as topermit the jewels to communicate with the interior of the structure,while the balance of the walls of the plastic material structure shouldbe of suiiicient thickness to give the required strength.

In the present case the core is shown constructed in ten sections, twosections 3 and 4 arranged diametrically opposite each other and eightsegment-shaped sections 5 extending in curved lines from the respectivesections 3 and 4:- Each of the sections 5 has a shouldered engagementwith the respective sections 3 and 4. After the sections are assembledthey will be held in position by wires 6 which extend throughperforations in the section 4 and eyelets 7 on the interior of therespective sections 5 and are connected as at 8 to the section 3. Bydrawing these wires taut and securing them, it will be seen that all ofthe sections will be held securely together. One of the sections 5 hasboth of its sides formed parallel to permit it to be removed in thisassembling of the core. For instance, it will be seen that the side 5 ofone of the sections is parallel with the opposite side of said section,the side of the adjacent section being shaped to conform thereto, sothat this particular section with the parallel sides may be readilyremoved so soon as the section a is taken out, thus giving room for theseparation of the balance of the sections 5. To prevent the section withthe parallel sides from pulling out when its wire is tightened, suitablefastening devices are provided between it and the adjacent section,these fastening devices being in the nature of bars 9 which pass throughkeepers 10 on the respective sections, these bars being removed byinserting the hand through the opening left by the section 4. Anotherform of section core can be constructed of material which can be readilycrumbled, such as a mixture of sand and wheat flour.

The walls 1 of the mold will be formed with a series of openings toreceive the ornaments during the molding operation, and these openingswill be of such relation to each other as to give the proper effect anddesign desired. For instance, in the present case, there is shown threeseries of openings extending completely around the mold and theornaments will be held in these openings during the molding operation inthe following manner, reference being had more particularly to Fig. 3for detail. 11 represents an opening in the wall 1 and 12 represents themain body of the ornament, a reduced rounded portion 13 of whichprojects through the opening, the shoulder 14: formed by the main bodyand the reduced portion being held against the inside of the walls 1 inthe following manner: 15 represents a bridge which may be in the natureof a flat spring. The portion 13 of-the ornament has secured thereto,preferably by gluing, a piece of fabric 16 to which fabric is removablysecured a screw-threaded pin 17 which extends through the center of thebridge 15 and receives a thumb nut 18 so that by screwing the thumb nut18 down upon the bridge, the ornament will be drawn against the interiorof the walls 1 and held in this position. The pin 17 is secured to thefabric by providing the end of the pin with an eye 17 to receive a hook16 which projects from a concave plate 16 placed between the ornamentand fabric. The main body 12 of the ornament has its sides beveledoutwardly so that after the cement, which is represented by 19, ispoured about the same, the ornament will be firmly embedded therein andprevented from slipping in either direction from the finished casting.The lower end of the ornament has a reduced portion 20 which receives asoft rubber cap 21 which serves the purpose of providing an opening inthe finished casting for light penetration and also to allow for morethickness of material in the wall of the casting at this point. This capalso provides for making a good contact on the surface of the core. aring 22 of soft rubber is also preferably placed about the main portion12 just beneath the walls 1 to prevent displacement of water or sandthrough leakage caused by any imperfect contact of surface of theornament to the inner surface of the walls of the mold. After thecasting has been made and removed from the mold, these rubber caps andrings are removed. After the cement or other plastic material has becomeproperly set in the mold, the thumb screws 23 are removed from the endsof the wires 6, which permits the section 4: to be removed, after whichthe section 5 and the section 3 are removed, in the manner beforeexplained. By assembling the thumb screws 18, the bridges 15 may beremoved from the pins 17 and then the pins detached from the fabric 16.The fabric 16, as before stated, being preferably glued to the jewels13, may be readily removed therefrom by moistening and scraping. Thewalls 1 may be removed before or after the removal of the. core, leavingthe finished product ornamented with the jewels or embellishmentsdescribed.

In Fig. 6 there is illustrated a slight modification in which there isshown a bushing 2: a inserted in the opening 11, the walls of the moldabout the opening being shouldered to receive this bushing. The bushingis held in place by clamps 24c pivoted to the walls of the mold byscrews 25. By first removing these bushings, it will be seen that thewalls of the mold may have a greater altitude of movement toward theornaments so that it will not be necessary to make the walls of the moldin as many sections as in the construction shown in Fig. 3.

Structures of plastic material may be thus constructed in many differentforms and used for porches, gate entrances to drive ways, ornamentalcement work for lawns, parks and the like, and in fact for any cementwork to which it is desired to give an ornamental appearance. By castingthe cement structure hollow and illuminating it in any desired way, apleasing illuminated effect may be given to the structure by employingdifferent colored jewels arranged in tasty designs. In order to preventthe ornament from turning in the casting, the main portion 12 thereofmay be provided with one or more recesses 12, into which the plasticmaterial will enter so as to make an interlocking olnt.
